In this chapter we explain the physics of the motion of charged bodies - especially the formula of the Lorentz-force. To demonstrate how the force takes effect, we consider the behavior of an electron flying through a magnetic field. Absolute beginners should start with this part.

The general description of the motion of an electron in a magnetic field constructed in Chap.1 is our starting point for Chap.2. To get a deeper understanding we intend to solve the equation of motion as well as give concrete examples for movements.

This part deals with the developing of the physics a starship driven by photon pressure. To simplify the situation we assume that the technique of the accelerating system (laser, Fresnel zone lens, ...) compensate effects like the Doppler-effect, so the beam power received (and reflected) from the starship stays at constant levels. Then we intend to use our results to find a complete route for our starship: the ship starts at our solar system for a 23-year long journey to Epsilon Eridani.
